A youthful sea-god, probably Triton (though perhaps Thaumas or one of the other more obscure gods), guides a Hippokampos (fish-tailed marine horse) on a rein. The sea-god is portrayed as an Ikhthyokentauros, a merman with equine forelegs and lobster horns. He holds an anchor (?) in his hand. Behind him follows a second sea-god. This red-skinned figure with fish-tail, lobster-claw forelegs and horns, is probably Phorkys.
